These two charts are great. Great from a things that make you go "hmm" stand point. The chart on the left is the US marriage rate starting about 1965. The chart on the right is the proportion of women in statewide executive office. Governors, Attorneys General, Secretary of States, etc etc.
In about 1971 the US marriage rate began a steady and slow decline, at about the same time the amount of women winning and holding statewide elected office began to increase. Of course this is my obligatory "correlation is not causation" line here, but it sure does make you think.
I for one welcome more women in politics, in a democracy diversity is always a good thing. I am just interested in the relationship of two seemingly unrelated variables how they potentially impact one another.
